Closure for roll-on applicator

Abstract

A closure adapted to use on a roll-on dispenser and especially in connection with dispensing a liquid composition containing a major quantity of a liquid volatile silicone; said closure including a skirt depending from the inner surface of the roof of the closure which skirt serves as a sealing means when the closure is mounted on the roll-on dispenser, said skirt being provided with a plurality of supporting braces which prevent the flaring of the skirt when it is mounted in sealing engagement on the dispenser.

What is claimed is: 
     
       1. In combination a closure and a dispenser container, said dispenser container comprising a container body having an upper open end and rotatable applicator; said rotatable applicator being removably mounted in the upper end of said container by means of a flexible retaining means, said flexible retaining means being adapted to be urged inwardly toward said rotatable applicator thereby forming a seal sealing the interior of said container from the atmosphere; said closure comprising a cap being provided with an upper inner surface and a lateral inner surface, skirt means provided with an inner surface and depending from and being integral with said upper inner surface of said cap; said skirt means being spaced inwardly of said lateral inner surface of said cap; said skirt means also being provided with bracing means to prevent deformation of said skirt means when pressure is applied to said skirt means when the said closure is mounted on said dispenser; said bracing means comprising a plurality of radially disposed bracing ribs secured to and extending inwardly of said inner skirt means surface; said skirt means being sufficiently long and adapted to apply pressure on said retaining means to urge the latter against said rotatable applicator means when said closure is in place on said roll-on dispenser. 
     
     
       2. The combination according to claim 1 in which said closure takes the form of a hollow cylinder having a horizontal roof that is essentially perpendicular to the said skirt means. 
     
     
       3. The combination according to claim 2 in which said skirt means also has the form of a hollow cylinder that depends from the undersurface of said roof. 
     
     
       4. The combination according to claim 3 in which the lower margin of said skirt means is provided with a bevel which is adapted to engage said flexible retaining means. 
     
     
       5. The combination according to claim 4 wherein the internal surface of said closure walls are threaded and adapted to be screwed on to said container.
